Property as an investment

Property in Thailand as an investment

If your primary objective is rental income, capital appreciation or a future resale, you should assess the Thai market more objectively from the outset than someone buying a home for personal use.

Analysis of a property purchased as an investment in Thailand

Three questions before reservingHow much will the capital really earn? Is the rental model legal? How much will you sell the unit for later?

A sales offer and a good investment are not always the same thing.

A clear-headed analysis before the emotions

Thailand may offer interesting investment opportunities. At the same time, it is a market where it is very easy to confuse a well-prepared sales offer with a well-prepared investment.

An infinity pool, an attractive location, beautiful visualisations, foreign quota and a promised 7–10% per year do not yet answer questions about value, rental compliance or the possibility of selling later.

01Property value first. The promised percentage comes later.

Investor comparing projects and financial assumptions with a local adviser — Compare the price with completed units and the resale market before adding a projected return.

Check the property price first, then consider the promised return

One of the most common mistakes is to begin the analysis with the statement:

“The developer guarantees 8% per year for five years.”

It is much more important to establish first:

What is this property really worth without the guaranteed-return programme?

Compare it with:

other new projects in the same area,
completed developments,
similar units several years old,
resale-market listings.

On Phuket, the difference between the primary and resale markets is already very clear. C9 Hotelworks data indicated a median of approximately THB 139,000/m² in the primary market versus approximately THB 100,000/m² in the resale market for unbranded condos. In Cherngtalay, the figures were approximately THB 147,000 and THB 108,000/m² respectively, while in Karon they were approximately THB 148,000 and THB 103,000/m². (C9 Hotelworks)

This does not mean that every apartment automatically loses 20–30% of its value.

It does, however, show an important characteristic of the market:

*a new project is often sold at a premium for being new, as well as for marketing, instalment plans, furnishings, agent commissions and additional promises.*

After several years, the owner is selling an ordinary used apartment.

“Guaranteed 7–10%” – understand where the money comes from

A guaranteed-return programme does not automatically mean that an investment is bad.

It may be convenient for a client who does not want to manage the property personally.

The problem arises when the guarantee replaces an analysis of the price.

Imagine two similar units.

One costs THB 4 million.

The other costs THB 5 million, but the seller guarantees 8% per year for several years.

In this situation, you need to ask a very simple question:

*have I already paid part of the future “return” through the higher purchase price?*

Economically, this is entirely possible.

This does not mean that every such programme works in this way. It means that you need to distinguish between:

*the value of the property*

and

*the value of the marketing package attached to the sale.*

The best test is to compare the price with similar units in the same micro-location – particularly on the resale market.

Viewing a several-year-old apartment on Thailand’s resale market — In a few years, today’s new project will be an ordinary used apartment competing with the next wave of launches.

The resale market matters as much as the new-project market

This is a subject very often overlooked when investment properties are sold.

A new project has:

a sales office,
agents,
commissions,
advertising,
visualisations,
instalment plans,
promotions,
furnishing packages,
and sometimes a rental guarantee.

Five years later, a private owner usually has:

*one used apartment to sell.*

And a potential buyer can walk a few hundred metres further and buy something new.

On Phuket, this is not merely a theoretical issue. Krungsri estimates that at the end of 2025 there were 14,008 unsold residential units, of which 12,346 were condos. The total value of unsold property increased to approximately THB 193.7 billion. (krungsri.com)

Colliers also indicates that substantial condo supply is putting pressure on absorption, particularly in projects that do not stand out through their location or product. (Colliers)

Therefore, an investor should ask not only:

*“how much will I earn from rent?”*

but also:

*“who will I sell this property to in 5–10 years?”*

Short-term rentals

The income model must have a legal basis

Short-term rentals – the rule here should be clear

This is one of the most important points in the entire guide.

If you are buying an ordinary apartment in a Thai condominium and plan to rent it independently to tourists by the day or week, do not assume that this is a legal business model.

Thailand’s Hotel Act treats paid, temporary accommodation for travellers as hotel business activity. The definition of a hotel excludes accommodation intended exclusively for monthly or longer-term rental. (ThaiLawOnline)

Even more important is the position of the Department of Lands regarding condominiums.

In November 2023, Thailand’s Department of Lands clarified that units in a building registered as a condominium may not be used to operate a hotel business. Consent from co-owners or the building management does not change this rule. For the building to operate as a hotel, its condominium registration would first have to be removed, followed by compliance with hotel law and other applicable regulations. (Tilleke & Gibbins)

This has a very practical implication

When buying a standard condo, you should not base your calculations on the assumption:

“I will buy a unit, list it on Airbnb and rent it to tourists for 3–7 days.”

If the investment model depends on this type of rental, its legality must be established first, and only then should the potential return be calculated.

The fact that a management company is licensed does not always solve the problem

This is highly important.

It is not enough to find a company that:

manages Airbnb listings,
welcomes guests,
cleans the property,
sets prices,
has hotel-industry experience.

The operator’s licence or authorisation must permit services to be provided at the specific property and within the specific legal structure.

If the unit is in an ordinary building still registered as a condominium, an agreement with a management company does not automatically turn the condo into a legal hotel. The Department of Lands’ position is unequivocal on this point. (Tilleke & Gibbins)

Before buying, it is therefore worth asking the seller to answer in writing:

on what legal basis short-term rental is possible,
who the formal operator is,
which document or licence covers the property,
whether the building is actually authorised to conduct hotel business,
who is responsible for taxes and guest registration.

The statement:

“everyone here rents this way”

is not a legal basis.

Do not base your calculations on the statement:“I will buy an ordinary condo, list it on Airbnb and rent it to tourists for a few days.”

First obtain written confirmation of the legal basis for the specific unit, building and operator.

Enforcement and building controls

Reception desk and access control in a modern condominium in Thailand — Electronic access improves security, but it also makes it easier for management to observe frequent guest turnover.

Inspections are no longer merely a theoretical risk

A few years ago, part of the market operated relatively freely in practice.

In 2025 and 2026, however, enforcement became much more visible.

Thailand’s Department of Provincial Administration conducted inspections and proceedings involving condos rented by the day in both Bangkok and Phuket. The authorities officially indicated that daily rental of condominium units violates the Hotel Act. (Government of Thailand)

The penalty for operating a hotel business without the required licence may include:

up to one year’s imprisonment,
a fine of up to THB 20,000,
or both penalties,
plus up to THB 10,000 for each additional day that the violation continues. (ThaiDeka)

This does not mean that every Airbnb owner will be inspected the next day.

It does mean that the risk can no longer honestly be treated as purely theoretical.

“But everyone here does it”

This is a common argument.

The problem is that toleration of a practice for several years gives the owner no right to continue it in the future.

An inspection may begin after:

a resident’s complaint,
a conflict with building management,
an inspection of the entire building,
a report by a competitor,
action by local authorities.

On Phuket, recent condo inspections were conducted partly in response to residents’ complaints. (Phuket News)

Therefore, an investment of several million baht should not be based on the strategy:

“No one is objecting for now.”

Modern buildings are increasingly able to control access

New projects increasingly include:

access cards,
resident registration,
electronic guest systems,
lift controls,
surveillance,
facial recognition.

From residents’ perspective, this improves security.

From the perspective of an owner conducting unauthorised short-term rentals, it means that regular tourist turnover is increasingly difficult to conceal from building management.

In older buildings, it was sometimes possible for years to hand over a key and admit successive guests completely anonymously.

In a new condo, this may be technically very difficult.

Income after tax

Platform revenue is not yet profit

Rental tax must also be calculated

Property rental income in Thailand is subject to Thai tax rules.

Revenue Department classifies income from property rentals as taxable income. (กรมสรรพากร)

Airbnb also clearly informs hosts in Thailand that hosting income may be subject to income tax and, at sufficiently high turnover, VAT. (Airbnb)

Furthermore, the Thailand tax guide prepared for Airbnb expressly warns that Airbnb may be required to report platform users’ income, and discrepancies between platform data and a taxpayer’s return may lead to questions from the tax authorities. (Airbnb Assets)

Airbnb also reserves the right in its privacy policy to disclose host data to tax authorities and other authorities where permitted or required by law. (Airbnb)

Therefore, you should not assume:

“The money comes through a foreign platform, so the Thai authorities will not see it.”

How long should you allow for a tax inspection?

There is no single simple figure for every situation.

Thailand’s Revenue Department states that some tax records must be retained for at least 5 years, while in certain cases the period may be extended to 7 years. (กรมสรรพากร)

In some situations – for example, where a return was not filed or the tax base was significantly understated – the period during which the authorities may assess tax may extend to 10 years. (กรมสรรพากร)

Therefore, the strategy:

“After a few years, everything will disappear”

is not a reasonable investment assumption.

Investment resilience test

A guaranteed return should be an addition, not the foundation of an investment

It is also worth reading the operator agreement carefully.

Check:

how long the guarantee applies,
who finances it,
whether the operator can renegotiate the terms,
what happens after the guaranteed period ends,
who pays for furnishings and repairs,
who bears the cost of vacancy,
whether the owner may use the property personally,
what conditions apply when the agreement is terminated.

If the entire financial result of the investment looks attractive only during the first 3–5 years of the guaranteed programme, you also need to calculate year six.

The best test: deliberately make the calculation worse

If the seller shows:

8% return, calculate 5%.

If the assumption is:

80% occupancy, calculate 60%.

If the forecast is:

30% property-value growth, calculate 0%.

If the investment still looks good after this test, it starts to become interesting.

If a small change in assumptions causes the entire calculation to stop working, you are probably buying an optimistic scenario, not a resilient investment model.

Thailand’s property market is not bad – it is more demanding than the marketing suggests

Thailand still has many genuine advantages:

a huge tourism market,
Bangkok as a global metropolis,
Phuket’s international profile,
developing infrastructure,
a substantial expatriate community,
demand for medium- and long-term rentals,
the growing Eastern Economic Corridor.

For these reasons, property can be an interesting investment.

But a good investment should not require you to believe in:

ever-rising prices,
full Airbnb occupancy all year,
an absence of inspections,
tax anonymity,
a future buyer willing to pay any price.

Owner and operator checking the furnishings of an apartment intended for rental — Stable rental income requires a real operator, property maintenance and costs calculated on the owner’s side.

What may make more sense than classic “nightly Airbnb”

In many cases, a considerably more stable model may be:

monthly rental,
medium-term rental,
rental to expatriates,
rental to people working in Thailand,
a legal hotel project,
a properly registered small accommodation business,
a project operated under a legal structure covering the specific property.

This will not always generate the highest gross nightly revenue.

It may, however, mean significantly lower legal risk and a more predictable business model.

Local analysis and coordination

How we can help

We work with agencies, project owners and developers, but we begin by analysing whether the proposed model can operate for many years.

At ThaiPol, we work with trusted agencies, project owners and developers in different parts of Thailand.

We can help you:

compare projects,
check the location,
compare primary- and resale-market prices,
gather information about the foreign quota,
analyse the proposed rental model,
check the terms of the operator programme,
put the client in touch with an independent lawyer or accountant,
assess the property not only for purchase, but also for a future exit from the investment.

We do not want to begin with the question:

“Which project should we sell you?”

For an investment, the much more important question is:

“Can the model presented to you really operate for many years?”

Checklist before signing

Key questions before an investment purchase

Before signing an agreement, it is worth obtaining clear answers to several questions:

Do I know the property’s real value without the promotional programme?
How much do comparable units cost on the resale market?
Is short-term rental legal in this specific property?
Which document confirms this?
Who formally operates the hotel business?
Does the building administrator permit this model?
How will taxes be accounted for?
What will the actual net income be?
What happens after the guaranteed return ends?
How many comparable units are currently for sale?
Who will I be able to sell the unit to in 5–10 years?
What happens to the calculation if prices do not increase at all?

If the figures still look attractive after answering these questions, it is worth moving to the next stage.

If the model begins to fall apart after two or three questions, it is better to discover this before signing the agreement and transferring the money.

Exceptions must be read carefully

When can short-term rental operate without a full hotel licence?

Finally, the exceptions should be explained very precisely, because “without a hotel licence” does not mean “without any formalities”.

1. Monthly or longer-term rental

The Hotel Act excludes accommodation intended exclusively for monthly or longer-term rental from the definition of a hotel.

This is therefore not hotel-style short-term rental and does not require a hotel licence on that basis. (ThaiLawOnline)

2. Small accommodation business: maximum 8 rooms and 30 guests

Following regulatory changes in 2023, a small accommodation business may operate without a full hotel licence if it has:

a maximum of 8 rooms in total in one or more buildings,
a maximum of 30 guests,
and meets the other requirements for the category “สถานที่พักที่ไม่เป็นโรงแรม” – accommodation not classified as a hotel. (DSS-Sciinfo)

But the exception does NOT apply automatically

The operator must:

notify the appropriate registrar,
submit the required documents,
pass an inspection of the property,
receive written confirmation that the notification has been accepted.

Only then is the property not treated as a hotel requiring a full licence. Ministerial regulations provide for written confirmation after inspection, while official DOPA procedures provide a separate process for such accommodation. (Thailand Law Online)

In other words, a small resort with, for example, 5 bungalows cannot simply say:

“We have fewer than 8 rooms, so we do not need any authorisation.”

If it wants to accept paying guests for short stays, it should follow the appropriate procedure and obtain หนังสือรับแจ้งสถานที่พักที่ไม่เป็นโรงแรม – confirmation of notification for accommodation not classified as a hotel.

3. This exception does not legalise an ordinary condo

This is very important.

Government procedures for notifying small accommodation businesses refer, for example, to houses, guesthouses, pool villas and small accommodation properties. The official DOPA procedure expressly states that condominium units cannot be notified under this procedure. (Info Go)

Separately, the Department of Lands has explained that a condominium cannot operate a hotel business unless its condominium status has first been terminated. (Tilleke & Gibbins)

Therefore, the 8 rooms / 30 people rule should not be interpreted as follows:

“I have one condo, so I am below eight rooms and can legally rent it on Airbnb.”

*No – for a standard condo, this exception is not a straightforward route to legal nightly rental.*

4. Full hotel licence

If the property does not qualify as a small accommodation business operating without a licence, or exceeds the limit of 8 rooms / 30 guests, short-term activity requires an appropriate hotel licence and compliance with requirements concerning the building, safety, use and other regulations. (Tilleke & Gibbins)

The simplest rule to remember

*Ordinary condo + nightly rental = do not assume that it is legal.*

*Small guesthouse, pool villa or resort ≤8 rooms / ≤30 guests = a simplified route without a full hotel licence may be possible, but it still requires official notification, inspection and confirmation.*

*Monthly or longer-term rental = a separate category outside typical hotel activity.*

That is precisely why, before buying a property “for Airbnb”, the basic question should not be:

“How much can I charge per night?”

It should be:

“On what legal basis can I sell that night at all?”
